Ballast Feedback

[chpthril]

Anecdotal evidence shows me that my 1200 GPH Tsunami (aerator) fills my bow sack in less time than my Ballast Puppies (650 GPH impeller). I think the reason is that as the sack gets pressurized, the impeller pump still pushes 650 GPH and the aerator pump drops off dramatically.

do you mean "more time"?

That would stand to reason if the aerator pump was filling from the bottom as they are not designed to build pressure such as the weight of 400# of water.

Most aerator setups seem to be filling from the top so there is no back pressure unless the sac is not venting. I'm really interested in doing a head-to-head and see.

Ignition protected means the electrical portion is insulated so it contains any sparks and is safe to use in the bilge and engine bay of a boat. Any stray spark could ignite the heavy gas fumes that can accumulate and settle in the bilge. Things like starters, alts, bilge pumps, etc are IP. You can get non-IP pumps that will go in the cabin area for things like sinks and heads. If someone is going to use the impeller type pumps and mount them anywhere in the back, such as where the batteries, etc, are stored, or in the engine area, they REALLY should use IP pumps.

If that's true, I'd like to ask for a free ballast system and install, please!

I'll meet you half way, how 'bout cost and you can tell all your friends how good it is and how easy it was to install

That sounds great to me! Now, I just need to convince my wife...

I put together my own system. I had to work out the vapor lock issue which was caused by 2 factors. Placement of checkvalves and the manifold I build with expansion for a 4th fill pump. I made an air relief valve on the manifold to release the trapped air in the 4th pump location and moved the check valves at the same time. It cured the issue but not sure of which change or the combination of both solved the issue.

If I was going to do again I would use the aerator pumps for the rear based on cost and use a reversible pump for the bow bag. I love how the bow bag fills but would like to be able to drain more out of it. I might add a simer pump in the offseson as the drain pump on the bow bag and use the existing tsunami bow drain pump as the 4th fill pump to speed the filling of my custom surf sacs

How about a couple of 1600gph aerator pumps in place of your surf sac t1200's. They should fit your current manifold, use the existing wiring, and have a 1-1/8" outlet like the T1200.

I am just going for the cost factor. When I replace my bow drain pump with the simer for draining I have an extra tsunami. Will screw right in to the manifold and I already have the wiring and hose there for the 4th pump. Just need the quick connect for the bag and I am done. If I am motivated I will put a t in and be able to divert the 4th pump fill to either surf sac.

The simer is $85 and will fit in the compartment with my sub box.

xpjim1-- How did you create a relief valve at the end of the manifold, I think I may need one.

I built my manifold for 4 pumps and only used 3. In the attached link you can see the spot labeled #4. I put an elbow there and ran a hose straight up and put a check valve on the end. Not really sure if it was the issue as I also moved my check valves to the bag side as this prevented the water in the hose keeping the valve shut.
